The soul of Shen Yan, a doctor of modern criminal investigation chemistry, has passed through the death row prisoners of the Dayao Dynasty. He relies on criminal investigation methods that fit the ancient background (fingerprint extraction, poison testing, logical reasoning) to solve various strange cases. During the investigation, he and the Queen of Dayao Chu Zhaoning and General Qin Shuyan of Zhenbei , Xiao Qingyi, the Crown Princess of the Southern Chu Dynasty, and Yehenara Yunqi, the Queen of the Beihan Khanate, are deeply bound. The emotional line runs through "testing - bonding - guarding - staying together". The case conforms to the logic of ancient justice, people's livelihood, and power strategy, and there is no sense of violation of advanced technology.
